怎么改变ToolBar背景色

只改变背景色，懒得去网上找来找去了，直接在MSDN上看了下属性

TBSTYLE_FLAT 

Version 4.70. Creates a flat toolbar. In a flat toolbar, both the toolbar and the buttons are transparent and hot-tracking is enabled. Button text appears under button bitmaps. To prevent repainting problems, this style should be set before the toolbar control becomes visible. 

上代码:

case WM_CREATE:
		{
			LRESULT lResult = CallWindowProc(oldWndProc, hWnd, uMsg, wParam, lParam);
			CToolBar *ptest = (CToolBar*)CWnd::FromHandle(hWnd) ;
			if (ptest)
			{
				ptest->ModifyStyle(0,TBSTYLE_FLAT );
			}
			return lResult ;
			
		}
		break;
	case WM_ERASEBKGND:
		{
             CRect rcClient ;
			 ::GetClientRect(hWnd,&rcClient) ;
			 CDC *pDC = CDC::FromHandle((HDC)wParam) ;
			 pDC->FillSolidRect(rcClient, RGB(240, 0, 30));

			 return TRUE ;

		}
		break ;
